转型背景下地方高校新同质化问题思考?

地方高校在转型过程中陷入了新同质化的困境,出现了侧重向工科专业投入建设的一边倒倾向,过度强调就业技能等问题,偏离了政府对地方高校转型的目的。地方高校在转型中应找准定位,将传统优势与地方资源需求相结合,相关专业互融支撑,创办特色专业,从而实现错位化、差异化的发展。还要利用优质智力资源,及时更新、动态调整专业设置,发展社会急需的新专业,从而实现地方高校真正意义上的转型,为地方高校的生存争取更大的空间。     

陕西地方院校高层次人才引进策略研究?

陕西地方院校长期存在着学校知名度不高,教师收入水平低,高层次人才储备不足、引进困难和增长缓慢的不良现状。为改善这一现状,有效加强高层次人才引进工作力度,陕西地方院校应以重点学科为突破点,以实际需求为导向,牢固树立成本意识,理性制定高层次人才引进策略;应增强引才主动意识,积极学习西方发达国家引才理念,善于利用政府牵引模式下的高层次人才引进合力,全面活化高层次人才引进手段;应注重经济契约与心理契约有机结合,刚性管理与柔性管理有机结合,将团队建设纳入考核内容之中,切实加强对高层次人才的管理。     

真实性偏好如何影响全球品牌中国元素产品的购买可能性?

在中国市场上,全球品牌本土化的现象越来越频繁.但在理论上,还少有研究分析中国消费者如何评价融入中国元素的全球品牌.为此,文章以认知—情感人格系统理论为框架,构建了包含真实性偏好、品牌本土象征价值、尊重品牌遗产和购买可能性的概念模型,试图探索其中的因果关系.实证研究表明,品牌本土象征价值认知—情感单元和尊重品牌遗产认知—情感单元均能提高购买可能性.真实性偏好高的消费者更容易通达品牌本土象征价值认知—情感单元和尊重品牌遗产认知—情感单元.尊重品牌遗产认知—情感单元有助于增强品牌本土象征价值认知—情感单元.文章不仅在理论上丰富了全球品牌相关研究,同时对实践也有战略指引.     

PPP模式在政府债务危机中的应用研究

近年来,政府债务危机频频爆发,国务院办公厅下文要赋予地方政府适度举债融资权,规范地方政府的举债融资机制.政府与社会资本合作模式(P P P模式)被列入规范政府举债融资机制之中,该举措对于化解地方政府债务压力,缓解公用基础设施建设资金短缺发挥重要作用.因此需要对PPP模式适用于政府债务领域的可行性和必要性进行分析,在缓解政府债务的PPP具体模式中加以选择,并从法律层面保障PPP模式的实施.     

Inference in Semi‐Parametric Dynamic Models for Repeated Count Data

This paper deals with a longitudinal semi‐parametric regression model in a generalised linear model setup for repeated count data collected from a large number of independent individuals. To accommodate the longitudinal correlations, we consider a dynamic model for repeated counts which has decaying auto‐correlations as the time lag increases between the repeated responses. The semi‐parametric regression function involved in the model contains a specified regression function in some suitable time‐dependent covariates and a non‐parametric function in some other time‐dependent covariates. As far as the inference is concerned, because the non‐parametric function is of secondary interest, we estimate this function consistently using the independence assumption‐based well‐known quasi‐likelihood approach. Next, the proposed longitudinal correlation structure and the estimate of the non‐parametric function are used to develop a semi‐parametric generalised quasi‐likelihood approach for consistent and efficient estimation of the regression effects in the parametric regression function. The finite sample performance of the proposed estimation approach is examined through an intensive simulation study based on both large and small samples. Both balanced and unbalanced cluster sizes are incorporated in the simulation study. The asymptotic performances of the estimators are given. The estimation methodology is illustrated by reanalysing the well‐known health care utilisation data consisting of counts of yearly visits to a physician by 180 individuals for four years and several important primary and secondary covariates.     

Nonparametric Estimation of the Number of Drug Users in Hong Kong Using Repeated Multiple Lists

We update a previous approach to the estimation of the size of an open population when there are multiple lists at each time point. Our motivation is 35 years of longitudinal data on the detection of drug users by the Central Registry of Drug Abuse in Hong Kong. We develop a two‐stage smoothing spline approach. This gives a flexible and easily implemented alternative to the previous method which was based on kernel smoothing. The new method retains the property of reducing the variability of the individual estimates at each time point. We evaluate the new method by means of a simulation study that includes an examination of the effects of variable selection. The new method is then applied to data collected by the Central Registry of Drug Abuse. The parameter estimates obtained are compared with the well known Jolly–Seber estimates based on single capture methods.     

一类含有随机参数的混沌系统的Hopf分岔研究

文章选取随机变量为系统的随机变量研究含有随机参数混沌系统的Hopf分岔,利用Chebyshev正交多项式逼近理论将含有随机变量的系统转化为等价的确定性系统,通过Hopf分岔定理和Lyapunov系数讨论了随机参数系统的Hopf分岔及稳定性,发现随机系统的渐进稳定性参数区间大小不仅和确定性参数有关,还与随机参数有非常密切的关系.     

英汉概数表达形式的结构类型比较

对汉英概数表达形式结构类型的比较能够在一定程度上反映汉英两种语言的特征及其所属文化的特征。通过系统性的比较可以发现,汉英概数表达形式之间存在四种同中有异的结构类型、三种不同结构类型。比较的结论表明,概数表达形式能够连用,但是连用的两类概数表达形式中肯定有一类用于表示推测。另外,汉语中存在逆序表达法,而英语中没有。与其他语言的比较可以得出相应类型学结论:逆序结构是概数表达形式的一种结构。     

An Empirical Process View of Inverse Regression

A common approach taken in high‐dimensional regression analysis is sliced inverse regression, which separates the range of the response variable into non‐overlapping regions, called ‘slices’. Asymptotic results are usually shown assuming that the slices are fixed, while in practice, estimators are computed with random slices containing the same number of observations. Based on empirical process theory, we present a unified theoretical framework to study these techniques, and revisit popular inverse regression estimators. Furthermore, we introduce a bootstrap methodology that reproduces the laws of Cramér–von Mises test statistics of interest to model dimension, effects of specified covariates and whether or not a sliced inverse regression estimator is appropriate. Finally, we investigate the accuracy of different bootstrap procedures by means of simulations.
